Kuroutoshikou Radeon RX Vega56 vs NVIDIA GeForce GTX 1080

Since both graphics cards have the same number of Raster Operations Pipelines (ROPs), and the GeForce GTX 1080 GPU is clocked higher, it also has higher pixel fillrate. Having better pixel fillrate allows the card to draw more pixels on screen and off screen, which is beneficial for some 3D effects in games, or when playing at higher display resolutions.

Although its graphics clock is slower, the Radeon RX Vega56 comes with better texture fill rate, owing to more TMUs (Texture Mapping Units). Better maximum texture fill rate means that the graphics card can apply more textures, utilize more sophisticated 3D effects for each texel, or render 3D image / game environment at higher resolutions without loss of detail.

Single Precision performance shows how many single-precision floating point operations the GPU can execute per second. The performance is expressed in billions of Floating Point Operations Per Second, or GFLOPS. Since FP calculations are performed by shaders, stream processors or CUDA cores, the performance is directly proportional to their number. Processor clock rate also affects it. The Kuroutoshikou Radeon RX Vega56 is faster here. Higher single-precision performance number means the graphics unit will perform better in general computing applications. Since stream processors or CUDA cores are also used as vertex and geometry shaders for 3D image generation, higher performance is also beneficial to games.

Maximum Double Precision performance is similar to the Single Precision performance, except that it applies to double-precision (64-bit) floating point operations. Games do not use double-precision arithmetics, therefore this characteristic is unimportant to their performance. The Kuroutoshikou Radeon RX Vega56 card has a very significant advantage here.

Memory bandwidth parameter tells how much memory (in Gigabytes) the GPU can read from or write to dedicated memory per second. Graphics cards with higher memory bandwidth have better performance at high display resolutions, or when using large and detailed textures, and/or utilizing complex 3D effects and filters, like anti-aliasing. The bandwidth depends on several components, such as memory type, speed, and width of memory interface. Specifically, the Radeon RX Vega56 graphics card offers wider memory bus. As a consequence, it has higher memory bandwidth.
